Dog Poker

Two dog owners were bragging about the intelligence of their pets. 

"The brightest dog I ever had," said one, "was a Great Dane that could play cards. He was a whiz at poker, but I 

had him put to sleep." "You had him put to sleep, a bright dog like that? A dog like that would be worth a million 

dollars." "Had to," he replied, "Caught him using marked cards!"
